STATEMENT OF RELATED APPLICATIONS

Not applicable.

BACKGROUND OF THE INVENTION

Throughout the years, people have sought to modify the color of theirskin, their eyelashes or their hair. Several techniques have beendeveloped to achieve the desired color.

It is known to dye human keratinous substrates, such as the hair, withdye compositions comprising oxidation dye precursors, which are alsoknown as oxidation bases. To vary the shades obtained with theseoxidation bases, additional couplers or coloration modifiers may beemployed.

It is also known to dye human keratinous substrates by direct dyeing,which comprises applying to the keratinous substrates direct dyes, whichare colored.

Traditional application time for dyeing keratinous substrates is aroundthirty minutes. Such a period is considered to be too long under currenttendency.

This problem cannot be solved by merely reducing the application time ofthe dyeing compositions since it would be difficult to maintain the samesatisfactory levels of coloring in shortened application times.

Another way to solve the problem is to increase the power of theoxidizing agent and the alkaline agent, by employing, for example,oxidizing agents of the type of the persalts, and/or alternatively byincreasing the pH of the dyeing composition. However, such an option isundesirable, because of the increased risk of degradation of thekeratinous substrates.

Therefore, there is a real need to develop dyeing compositions withimproved efficiency to yield minimum degradation of the treatedkeratinous substrates while achieving improved levels of coloring inboth conventional application time e.g., around 30 minutes and inshortened application times, e.g., around 15 minutes.

Another object of the present invention is to provide an effectivedyeing composition capable of depositing acceptable levels of color ontokeratinous substrates utilizing decreased levels of dye therein.

It is also desirable that such a composition can provide otheradvantageous properties to the hair such as shine, conditioning and ahealthy appearance.

Finally, it is an object of the present invention to provide aneffective dyeing composition with lowered cost of production.

In oneembodiment the oxidizing agents in the present disclosure are selectedfrom hydrogen peroxide, potassium persulfate, sodium persulfate andmixtures thereof.

Typically, the oxidizing agent is provided in the form of a developercomposition.

In one embodiment, the oxidizing agent is present in an amount of atleast 1% by weight, based on the total weight of the developercomposition.

In another embodiment, the oxidizing agent is present in an amountranging from greater than 0% by weight to about 40% by weight, or fromabout 0.01% by weight to about 30% by weight, or from about 0.1% byweight to about 20% by weight, or from about 1% to about 15% by weight,based on the total weight of the developer composition.

Developer Composition

The developer composition may be in the form of a powder, gel, liquid,foam, lotion, cream, mousse, and emulsion.

In one particular embodiment, the developer composition is aqueous or isin the form of an emulsion.

In another embodiment, the developer composition is substantiallyanhydrous. The term “substantially anhydrous” means that the developercomposition is either completely free of water or contains noappreciable amount of water, for example, no more than 5% by weight, orno more than 2% by weight, or no more than 1% by weight, based on theweight of the developer composition. It should be noted that this refersfor example to bound water, such as the water of crystallization of thesalts or traces of water absorbed by the raw materials used in thepreparation of the compositions according to the disclosure.

The developer composition can contain at least one solvent, chosen fromwater, organic solvents, and mixtures thereof.

When the developer composition is substantially anhydrous, the developercomposition may comprise at least one solvent chosen from organicsolvents.

Suitable organic solvents for use in the developer composition includeethanol, isopropyl alcohol, benzyl alcohol, phenyl ethyl alcohol,glycols and glycol ethers, such as propylene glycol, hexylene glycol,ethylene glycol monomethyl, monoethyl or monobutyl ether, propyleneglycol and its ethers, such as propylene glycol monomethyl ether,butylene glycol, dipropylene glycol, diethylene glycol alkyl ethers,such as diethylene glycol monoethyl ether and monobutyl ether,hydrocarbons such as straight chain hydrocarbons, mineral oil,polybutene, hydrogenated polyisobutene, hydrogenated polydecene,polydecene, squalane, petrolatum, isoparaffins, and mixtures, thereof.

The at least one solvent may, for example, be present in an amountranging from about 0.5% to about 70% by weight, such as from about 2% toabout 60% by weight, preferably from about 5% to about 50% by weight,relative to the total weight of the developer composition.

The pH of the developer composition can range from 2 to 12, such as from6 to 11, and it may be adjusted to the desired value usingacidifying/alkalizing agents that are well known in the art.

Cosmetically Acceptable Medium

The ready-to-use composition according to the disclosure can be invarious forms, such as in the form of liquids, creams, gels, lotions orpaste.

The ready-to-use composition can comprise other compounds constitutingthe cosmetically acceptable medium. This cosmetically acceptable mediumcomprises water or a mixture of water and at least one cosmeticallyacceptable organic solvent.

As examples of organic solvents, non-limiting mentions can be made ofalcohols such as ethyl alcohol, isopropyl alcohol, benzyl alcohol, andphenylethyl alcohol, or glycols or glycol ethers such as, for example,monomethyl, monoethyl and monobutyl ethers of ethylene glycol, propyleneglycol or ethers thereof such as, for example, monomethyl ether ofpropylene glycol, butylene glycol, hexylene glycol, dipropylene glycolas well as alkyl ethers of diethylene glycol, for example monoethylether or monobutyl ether of diethylene glycol.

Additive

The ready-to-use composition according to the disclosure can alsocomprise at least one additive used conventionally in compositions forapplication onto hair.

“Additive” means a substance that is added, different from the compoundsalready mentioned.

As examples of additives that can be used, non-limiting mentions can bemade of surfactants, antioxidants or reducing agents, penetratingagents, sequestering agents, perfumes, buffers, dispersants,conditioners, such as for example volatile or non-volatile, modified orunmodified silicones, film-forming agents, ceramides, preservatives,opacifiers, and antistatic agents.

Preparation and Application of the ready-to-use composition

According one embodiment of the invention, the ready-to-use compositionsaccording to the disclosure can be prepared from a dye compositioncomprising at least one direct dye as defined previously, with orwithout any developer composition.

According to another embodiment of the invention the ready-to-usecompositions according to the disclosure can result from mixing twounits, including a first unit of an oxidative dye containing compositionas defined previously and a second unit of a developer composition asdefined above, or vice versa.

According to yet another embodiment of the invention, a pre-treatmentcomposition containing at least one salt may be provided and appliedonto the keratinous substrates prior to the application of theready-to-use composition.

It has been surprisingly discovered that the composition of the presentinvention enables acceptable levels of dye to be deposited ontokeratinous substrates utilizing lower amounts of dye compared toconventional dyeing compositions.

Yet another surprising discovery is that in the event conventionalamounts of dye are employed, the dyeing process may be completed in lesstime such as 20 minutes or 15 minutes or 10 minutes, thereby causingless damage to the keratinous substrates.

In the event that conventional levels of dye are employed, coupled withconventional dyeing times, significantly larger color deposit onto thekeratinous substrate may be achieved.

Finally, the inventive composition contains large amounts of water,e.g., higher than 60%, or 80% by weight, which advantageously lowers thecost of production.

According to another embodiment of the invention, a kit for dyeingkeratinous substrates is provided, comprising:

a first unit containing, in a cosmetically acceptable medium: at leastone fatty monoamine compound; at least one nonionic surfactant; at leastone phosphate ester chosen from alkoxylated alkyl phosphate esters andalkyl phosphate esters; and at least one dye chosen from oxidation dyeprecursors and direct dyes; optionally, at least one thickening agent;optionally, at least one alkaline agent; optionally, at least one fattysubstance other than a fatty acid; and optionally, at least one salt;and

a second unit comprising at least one oxidizing agent and optionally, atleast one fatty substance other than a fatty acid.

According to yet another embodiment of the invention, the kit furthercomprises a third unit containing at least one salt in a cosmeticallyacceptable medium.

The invention will be further clarified by the following examples, whichare intended to be illustrative of the invention, but not limitingthereof.

EXAMPLES

The following example is intended for illustrative purposes only, and isnot meant to unduly limit the scope of the invention in any way.

Example 1 Low pH Blue Binary Color Deposit Study

A test swatch of 90% gray hair from IHIP, International Hair Importers,(1 cm width, 15 cm length) was dyed with 20 g of the mixture of thebelow dye composition mixed 1:1 with L'Oreal Majicreme™ 20 volumedeveloper. The pH of the final mixture was adjusted to 6.5 using NaOH.

Ingredients Example 1 DI Water Q.S. Oleamidopropyl Dimethylamine 2.0%PPG-5 Ceteth-20 11.0%  Oleth-10 Phosphate 2.0% Mineral Oil 1.0% N,N-Bis(2-hydroxyethyl) p- 1.47%  phenylenediamine Sulfate2,4-Diaminophenoxyethanol HCl 1.205% 

A control swatch was dyed with the mixture of Redken Shades EQ™ clear,containing the same dyes at same levels as above, mixed 1:1 with RedkenShades EQ™ Processing solution. The pH of the final mixture was adjustedto 6.5 using NaOH.

Both swatches were processed for 20 minutes at RT, rinsed for 1 minute(80 gph, 32° C.), and dried. L*a*b* values were measured before andafter coloring using Konica Minolta Spectrophotometer.

The final ΔL value measurements for the control and test swatches were−54.32 and −63.86, respectively. More negative ΔL value indicates darkercolor. The color intensity difference is also visually significant.Therefore the inventive formula deposits greater amounts of color on thehair than the control in the 20 minutes processes.

Example 2 High pH Blue Binary Color Deposit Study

A test swatch of IHIP 90% gray hair (1 cm width, 15 cm length) was dyedwith 20 g of the mixture of the below dye composition mixed 1:1 withL'Oreal Majicreme™ 20 volume developer. The pH of the final mixture wasadjusted to 9.5 using NaOH.

Ingredients Example 2 DI Water Q.S. Oleamidopropyl Dimethylamine 2.0%PPG-5 Ceteth-20 11.0%  Oleth-10 Phosphate 2.0% Mineral Oil 1.0% N,N-Bis(2-hydroxyethyl) p- 1.47%  phenylenediamine Sulfate2,4-Diaminophenoxyethanol HCl 1.205% 

A control swatch was dyed with the mixture of L'Oreal Preference™ basecontaining the same dyes at same levels as above, mixed 1:1 with L'OrealPreference™ 20 volume developer. The pH of the final mixture wasadjusted to 9.5 using NaOH.

Both swatches were processed for 20 minutes at RT, rinsed for 1 minute(80 gph, 32° C.), and dried. L*a*b* values were measured before andafter coloring using Konica Minolta Spectrophotometer.

The final ΔL value measurements for the control and test swatches were−54.32 and −66.92, respectively. More negative ΔL value indicates darkercolor. The color intensity difference is also visually significant.Therefore the inventive formula deposits greater amounts of color on thehair than the control in the 20 minutes processes.

Example 3 Wet Combing Study

Six untreated IHIP regular bleached hair swatches (1 inch width, 5.5inch length) were measured for Energy Break (the energy needed to combthrough the whole hair swatch), using the Instron wet combing machine.The swatches were then dyed with 15 g of the mixture of the below dyecomposition mixed 1:1 with L'Oreal Preference™ 20 volume developer.

Ingredients Example 3 DI Water Q.S Oleamidopropyl Dimethylamine 2.5%PPG-5 Ceteth-20 16.0%  Oleth-10 Phosphate 0.5% Mineral Oil 1.0%Resorcinol 0.550%  p-phenylenediamine 0.540% 

The dyed swatches were measured wet for final Energy Break reading. Theaverage Energy break readings of the untreated and the dyed swatcheswere 537.40 and 237.58 g-in, respectively. These values arestatistically significant. The average percent change in combing is−48.93, therefore the hair is about 49% smoother than before coloring.Thus, the inventive formula gives a better conditioning to the hair.
